During the holidays, I though about backupping. I wanted to have a simple backupping system that works automatically. That excluded
RAID (too complicated) and
DVD's (not automatic). Applications that seem to be useful in this regard include
Simple Backup Suite and
Unison. There is also a possibility to make a backup of the whole disc by using the
dd command. However, my solution was to buy an USB disc and do some
rsync+
cron magic. Pretty much similarly as described in
here.
